the jaw 12 of screw which is mov e parts shown in said the drawings. 10 indicates table type having a fixed on and a movient therewith and from the upon a rivet As is clearly is adjustably threads in a ably mounted in a suitable slideway in the frame 1.0. The slide-block 13 is connected to a movably mounted block llby means oi a pair of: toggle levers 15 and 16, the lever 16 being provided with an extension arm 17 formed rigidly therewith. A lever 18 is pivotally mounted upon a pin 19 adjacent to the lever 16, the arm 17 being provided with a pin 20 extending laterally therefrom through a slot 21 formed in the lever 18. Anotherlever 22 pivotally mounted upon a pin adjacent to the p n 1.9 isprovided at its free end with a laterally extending pin 24 which also projects through the slot 21 off the lever 18, the pin being provided with a roller 25 adapted to engage the edge of the arm 1?. By the use of the mechanism described, when the lever 18 is given a stroke toward the left in l 1 the lever 22 is also moved toward the lett serving to torce the arm l7 likewise toward the left, the roller being adapted to shift along the fare oi' the armlT toward the knuckle oi the toggle levers l5 and in for swinging such toggle levers into alignment. With the blozh 14 held in stationary position. the slide-block 13 will. he mov l downwardly by the operation as above described for effecting); the desired riveting operation. 7'

The means for operating the toggle levers :15 and 16 through the medium otthe levers l8 and 22 comprises a second pair of toggle levers 30 and F1, the lever 30 being pivotally connected at its outer end to the lever 18 and the lever 31 being pivotally mounted upon the frame 1.0 by means of a pin The pin 33 by which the toggle levers 30 and 31 are pivotally connected together provided with an enlarged head adapted to slide in dovetailed groove 3% formed in a lever 35 pivotally mounted upon the frame 10 by means of a pin 36. The lever is connected by means of a link 37 with a rotary member 38 in the form ot a gear. the construction bein such that upon a rotation of the gear '38 in counter-clockwise direction in Fig. l. the lever 35 is swung back and forth toward and from the left side of the machine as shown in said Fig. 1.. As will be readily understoodgrpon the movement oiithe lever 35 toward the left in said figure, the pin 33 is caused to move along" the slot 34 toward the axis of the lever -35,

serving to move the lever 18 toward the left for effecting an operative movement of the movable jaw 12. As is fully set forth in my prior application above referred to, the proportions of the parts are such that the toggle levers and 31 are brought into alignment with each other at or before the time when the lever 35 reaches the limit of its movement toward the left as above described. whereby the full toggle eifect is obtained. A pin 39 is provided upon the lever 35 for moving the toggle levers out of their aligned locking position as the le *er 35 swings toward the right.

The means for rotating the gear 38 comprises a motor 40 provided with a driving pinion 41 upon the motor shaft 42. Meshing with the pinion 41 is a gear 43 which rovolubly mounted upon a sleeve 44 which in turn is revolubly mounted in a sleeve 45 fixed upon the frame 10. As is shown in Fig. 3, the gear 43 is hollowed out in the form of a friction clutch member, A co-operating friction clutch member 46 is feathered upon the sleeve 44 so as to rotate therewith but to be free to slide longitudinally thereof. A spring 47 is interposed between the clutch member 46 and the end of the sleeve 44 serving normally to hold the clutch members out of engagement with each other. A rod 48 is mounted. loosely in the sleeve 44, be ing connected at one end with the clutch member 46 in such manner that movement of the rod 48 toward the right in Fig. 3 serves to throw the clutch members into operative engagement with each other against the action of the spring 47. As will be readily understood, with the clutch members out of operation, the gear 43 is adapted to run freely with respect to the sleeve 44. hen, however, the clutch members are thrown into operative engagement, the sleeve 44 is caused to rotate with the gear 43. A pinion 49 fixed upon the sleeve 44 meshes with the gear 38, whereby the motor 40 is adapted to drive said gear for effecting a riveting operation as above described.

Means is provided for moving the rod 48 toward the right in Fig. 3 for effecting an operative engagement of the clutch members. This means, in the construction shown, comprises a sleeve 50 fixedly mount ed upon the rod 48, said sleeve being pro vided with a cam 51 in the form of a screwthread adapted to co-operate with an internal screw-thread formed on the inner face of a bushing 52 carried by the frame 10. By the use of cam means of this type, upon a rotary motion of the rod 48, said rod is moved longitudinally with respect to the sleeve 44 for moving the clutch members into or out of operative engagement. The pitch of the thread 51 is such that when the rod is moved toward the right in Fig. 3 against the action of the spring 47,

the rod is automatically locked by friction against rotary motion in the reverse direction. The means for rotating the sleeve 50 and rod 48 for effecting the operative e11- gagement of the clutch members 46 and 43 comprises a plate 53 fixed upon the sleeve 50 and the rod 48 by means of a pin 54 as is best shown in Fig. 3. Revolubly mounted upon the sleeve 50 adjacent to the plate 53 is an arm or lever 55 which is provided with a socketed lug 56 within which is slidably mounted a pin 57, a coiled spring 58 being interposed between the pin 57 and the outer end of the lug for holding the pin yieldingly at the limit of its motion toward the right in Figs. 3 and 4. As is best shown in Fig. 4, the pin 5'? is adapted to extend into one of a series of openings 59 through the plate 53 for causing the plate to rotate with the arm or lever when such arm moved in clock-wise direction in Fig. 5. As is best shown in F 4 the outer end of the pin 57 .is beveled so as to permit motion of the arm 55 in counterclock-wise direction in Fig. 5 without causing a corresponding motion of the sleeve 50 and the rod 48. By the use of this construction, the arm or lever 55 is adapted to be used for turning the sleeve 50 and the rod 48 for effooting engagement the arm beingfree to turn in counterclock-wise direction in Fig. 5, either before or after an effective stroke of the arm, for being brought to the desired position upon the frame, this movement in counterclockwise direction in said Fig. 5 being effected without any change in position of the sleeve 50.

h'leans is provided for giving the sleeve 50 and the rod. 48 a rotary movement in re verse direction as compared with that effected by the arm for throwing the clutch members 43 and 46 out of engagement, such means being adapted to act automatically at the end of a complete rotation of the gear 38. This means comprises a pinion {i0 tired upon the end. of the sleeve 50 adjacent to the pinion 49. Mounted upon the gear It. so as to be brought into engagement with the pinion 60 there is a segmental gear 61, as is best shown in Fig. 2. The segmental gear 61 is mounted in position by means of bolts 62 extending through a circumferential slot 63 formed in the gear 38, the arrangement being such as to provide for an adjustment of the segmental gear 61. with respect to the As will be readily understood, when it is desired to effect a riveting operation, the arm or lever 55 is given a stroke in clockwise direction in Fig. 5 for turning the sleeve 50 and effecting a longitudinal movement of the rod 48. serving to bring the clutch memhere into engagement, the cam or thread. 51 acting automatically to hold the c utch of the clutch members.

members in continued engagement after the arm has been released. hen the gear 38 has been given a complete rotation for a single complete riveting operation, the segmental gear (31. comes into contact with the pinion (30 serving to rotate the pinion 60 .in counterclockwise direction in Fig. 2 for rotating the sleeve 50 and throwing the clutch members out oi engagement;

While I have illustrated and described the preferred form of construction for carrying my invent-ion into effect, this is capable of variation and modification without departing from the spirit of the invention. 1, therefore, do not wish to be limited to the precise details of the construction set forth, but desire to avail myself of such variations and modifications as come within the scope oi. the appended claims.
